SNx4AHC126 Quadruple Bus Buffer Gates with 3-State Outputs
1 Features
- Operating range 2V to 5.5V VCC
- Low delay, 3.8 ns (typical with 5-V supply)
- Latch-up performance exceeds 250mA per JESD 17
2 Applications
- Drive indicator LEDs
- Drive transmission lines with logic
- Enable or disable a digital signal
3 Description
The SNx4AHC126 devices are quadruple bus buffer gates featuring independent line drivers with 3-state outputs.
For the high-impedance state during power up or power down, OE can be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the drive.
